[0002] AGVs are short for automated guided vehicles, also known as automated guided vehicles or automated guided transport vehicles. They are unmanned, automated vehicles equipped with automatic guidance devices such as magnetic strips, tracks, or lasers, capable of traveling along pre-set paths to complete logistics handling tasks. AGVs are typically battery-powered and equipped with safety features and various auxiliary mechanisms, such as transfer and assembly mechanisms. Under the monitoring and task scheduling of a control computer, they can accurately follow a prescribed path and complete their tasks upon reaching the designated location. AGVs offer features such as automatic navigation, intelligent scheduling, precise positioning, safety, scalability, and flexible adaptability, making them widely used in the medical, electronics, food, logistics, and industrial production industries.

[0003] SMT steel mesh is a special mold for SMT. In the process of SMT steel mesh in and out of the warehouse, AGV equipment can be used to improve the work efficiency of SMT steel mesh in and out of the warehouse.

[0004] For example, the AGV equipment for material transportation with application number 202311171155.7 uses a differential wheel system to enable the entire equipment to move straight, sideways, and rotate in place, reducing the aisle area of the workshop, increasing the available area of the workshop, and improving the utilization rate of the workshop. The upper computer controls the opening and closing of the loading and unloading components, making the material transportation process controllable and reliable. However, the device still has certain defects;

[0005] Before transporting materials, they need to be placed in the loading assembly, and then taken out after being transported to the designated location. The efficiency of warehousing and out-of-warehouse is low, and it is not convenient to classify different materials, so the applicability is low.

[0006] Therefore, we proposed an AGV device dedicated to the automatic storage and retrieval of SMT steel mesh in order to solve the above problems. Summary of the Invention

The electric telescopic rod drives the mechanical material picking arm to move backward to take out the SMT steel mesh placement box, and then the first servo motor drives the transmission shaft to rotate, and the transmission shaft drives the material picking frame to rotate, thereby driving the SMT steel mesh placement box on the material picking frame to rotate, and changing the direction of the SMT steel mesh placement box. Then, the SMT steel mesh placement box is placed in a fixed position through the cooperation of the electric telescopic rod and the mechanical material picking arm.

[0015] Preferably, the width of the material picking frame is greater than the width of the SMT steel mesh placement box, and the mechanical material picking arm can adopt pneumatic drive technology to achieve fast and accurate grasping and releasing actions.
